Abstract

La présente invention concerne le domaine des dispositifs automatiques, et en particulier un dispositif de production automatique pour transformateurs de courant. La présente invention comprend une piste d'insertion de broche, une piste de boîtier, un manipulateur d'insertion de broche et un dispositif de commande. Le mécanisme de préhension du manipulateur d'insertion de broche saisit des broches en forme de L dispersées sur un dispositif d'alimentation de broche au niveau d'une extrémité de décharge de la piste d'insertion de broche, se déplace vers la partie supérieure du boîtier de transformateur saisi par un appareil de montage de boîtier au niveau d'une extrémité de décharge de la piste de boîtier, et insère la broche en forme de L dans un vérin dans le boîtier de transformateur. Les problèmes de faible efficacité d'installation, de faible rendement et d'endommagement de la maladie professionnelle au personnel en raison de l'insertion manuelle de broches de transformateur dans des procédés de production existants sont résolus.
